This press release notes success in a human trial of a heart therapy that "involves taking the patient's own bone marrow and purifying it to obtain the type of stem cells which will hopefully give rise to new blood vessels and muscle so the heart can get more oxygen and function better." The trial took place in Uruguay and was administered by a team of Argentinian researchers. Meanwhile, the FDA has been preventing US researchers from performing this sort of trial until very recently. Approximately 50,000 people worldwide die every day due to some form of heart disease. Political delays in research have horrific human consequences.
